ing notice to the Earl of Ormonde of the time, that his lordship might march out of Dublin to favour his retreat thither.’ On 26 Feb. a quantity of provisions was thrown into the town, and Tichborne seized the opportunity to make a sortie on the south side. As he was returning with hay and corn the enemy tried to intercept him at Julianstown Bridge, but were defeated with heavy loss. From this time the situation began to improve. Next day Lord Moore dislodged the besiegers on the north side, so that when Ormonde arrived with reinforcements early in March all imminent danger had passed away. The enemy were, however, still numerous in co. Louth. A plan for a joint expedition against them was forbidden by the government; but Tichborne and Moore, fearing lest the rebels might assemble in force again, determined to act by themselves. Accordingly, quitting Drogheda on 21 March with a thousand foot and two hundred horse, they marched in the direction of Dundalk, laying the country waste with fire and sword. At Atherdee they dispersed a number of the rebels, and on the 26th attacked Dundalk. After a short but sharp resistance the place was carried by storm. Its capture, being unexpected, afforded great satisfaction to government, and the defence of it was entrusted to Tichborne, Lord Moore succeeding him as governor of Drogheda.
On 3 April the king appointed him lord justice in the place of Sir William Parsons (1570?–1650) [q. v.], whose intrigues with the leaders of the parliamentary party had rendered him objectionable. His heroic four months' defence of Drogheda disarmed all opposition, and on 1 May he and Sir John Borlase were sworn lords justices. The arrangement was, however, intended only as a temporary one pending the appointment of the Earl of Ormonde as lord-lieutenant in the place of the Earl of Leicester. On 21 Jan. 1644 Tichborne and Borlase surrendered the sword of state to Ormonde in Christ Church, Dublin; and, shortly afterwards repairing to England, he, Sir James Ware, and Lord Brabazon were in December made the bearers of fresh instructions and powers from the king to Ormonde for the purpose of enabling him to conclude a definite peace with the confederate catholics. The ship in which they sailed was, however, captured by the parliament, and Tichborne and his companions carried to Portsmouth, and thence early in February 1645 to London. He was committed to the Tower on the 12th, and continued a close prisoner till September, when parliament consented to his exchange. Returning to Ireland and to his old post as governor of Drogheda, he was for some time regarded with suspicion by the parliament; but, having proved his devotion by his gallant conduct at the battle of Dungan Hill on 8 April 1647, a warrant was issued by the council of state on 5 April 1649 to pay him 200l. as a reward for his services on that occasion, and also another 300l. on account of 1,500l. laid out by him for the service of the state. His conduct appears not to have been approved by his wife, who separated from him, and, with Ormonde's assistance, sought a refuge in the Isle of Man.
During the Commonwealth Tichborne led a quiet and retired existence, but at the Restoration he was appointed marshal of the army. Early in 1666 he obtained a grant of the estate of Bewley or Beaulieu in co. Louth, forfeited by the attainder of William Plunket, which he henceforth made his residence. Here, on the site of the old manor, the headquarters of Sir Phelim O'Neill [q. v.] during the siege of Drogheda, he erected a fine seat, the hall of which, containing a number of family portraits, is particularly worthy of notice. His health failing him, he obtained permission on 12 Dec. to go with his family to Spa; but he was evidently unable to bear the journey, dying early the following year (1667) at Beaulieu. He was buried in St. Mary's Church, Drogheda, ‘which,’ observes Borlase, ‘owed a rite to his ashes, who, with so much vigilance and excellent conduct, had preserved it and the town.’
Tichborne married Jane, daughter of Sir Robert Newcomen, and by her, who predeceased him in 1664, he had five sons and three daughters: Benjamin, the eldest, captain of horse, killed at Balruddery, co. Dublin, aged 21; William, his heir, who married Judith Bysse; Richard, Henry, and Samuel; Dorcas, married to William Toxteth of Drogheda; Amphillis, wife of Richard Broughton; and Elizabeth, wife of Roger West of co. Wicklow.
Tichborne's grandson, Sir Henry Tichborne, Baron Ferrand (1663–1731), son of Sir William Tichborne, was born in 1663. At the time of the Revolution he ardently supported William III, and in reward was knighted in 1694, and created a baronet on 12 July 1697. He was advanced to the peerage of Ireland by George I on 9 Oct. 1715 with the title of Baron Ferrard of Beaulieu. He died without issue on 3 Nov. 1731, when his honours became extinct. In 1683 he married Arabella, daughter of Sir Robert Cotton, bart., of Combermere (G. E. C[okayne], Peerage).
